Vacuum question

I have a simple question that I have been wondering awhile and I just wanted to get some feedback on.

first off i have a 75g med planted tank.

when vacuuming do i want to just vacuum the surface of the gravel substrate or do i want to jam that thing down the inch or two to the bottom of the tank?

pretty simple question.

You don't want to disturb the roots and you want some of the mulm to be around the root/planted areas for the plants to use as food.
So IMO you don't want to jam the vacuum down around the plant root areas.....

I agree. I never vacuum in the gravelof my planted tanks except in the front areas where the bottom fish feed, to keep it clean; there are no plants in these areas. Except for this, I leave the mulm to sink in the substrate and be changed into nutrients by the bacteria. Wonderful plant food.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]

yep,me too,just the top layer,because my plec poopies
usually end up at the front,and it looks gross,however i have been known to
scoop the poop to the back for the plants.the vallis seem to thrive on it.

forgot to say welcome. :)

when you set up a new tank,hide an extra
sponge or two behind some decor,that way you have
something seeded for you next filter.

I just had to google the word mulm. I had no idea there was a technical term for undecomposed fish waste. Learn something new every day, I guess.
